The compounds according to the present invention may be prepared according to the following reaction schemes, in which, unless otherwise stated, the definition of each variable is as defined above for a compound of formula (I).

There are a number of alternative methods for preparing a compound of formula (I).

Method A

A compound of formula (I) may be prepared by reacting a compound of formula (II) with a compound of formula Het-C(═O)OR′ (where R′ is C₁₋₅ alkyl) in the presence of strong base [for example NaH or sodium hexamethyldisilazane], in a dry polar solvent [preferably THF] and at a temperature between −10° C. and the boiling point of the solvent [preferably at ambient temperature]. The article by J. Wang et al, Synlett 2001, 1485 provides details of analogous preparations.

Method B

A compound of formula (I) may be prepared by reacting a compound of formula (II) with a compound of formula Het-C(═O)R″ [where R″ is OH or a leaving group, such as Cl, Br, F or OC(═O)C₁₋₄ alkyl] in an inert organic solvent [such as ethylacetate, dichloromethane, dioxane or DMF] and at a temperature between −10° C. and the boiling point of the solvent [preferably at ambient temperature]. If R″ is OH, the reaction is carried out in the presence of an activating agent [for example BOP-Cl] and two equivalents of a base [such as a tertiary amine, an inorganic carbonate or a hydrogen carbonate]. Alternatively, if R″ is a leaving group, the reaction is carried out in the presence of at least one equivalent of base [such as pyridine, a tertiary amine, an inorganic carbonate or a hydrogen carbonate].

Method C

A compound of formula (I) [where R¹ is as defined above but is not hydrogen] may be prepared by reacting a compound of formula (I) [where R¹ is hydrogen] with a compound of formula R¹-L¹ [where R¹ is as defined above but is not hydrogen; and L¹ is a leaving group such as Cl, Br, I, a sulfonate (for example a mesylate or a tosylate) or OC(O)C₁₋₄ alkyl] in a solvent [such as a halogenated solvent (for example dichloromethane), an ether, ethylacetate, DMF or even water (as a biphasic rnixture, optionally in the presence of a phase transfer catalyst such as tetrabutylammonium hydrogensulfate)] and in the presence of a base [such as a tertiary amine, an alkali carbonate, an alkali bicarbonate, an alkali hydroxide or NaH; though if L¹ is O(CO) C₁₋₄ alkyl then simply heating without base is possible].

Method D

A compound of formula (I) may be prepared by reacting a compound of formula (Im) [where Hal is preferably bromo or iodo] with a compound of formula Het-C(═O)NH₂ in the presence of a Cu(I) compound and an aprotic solvent [such as a cyclic ether, for example dioxane] at an elevated temperature and preferably at reflux. The preferred conditions are CuI used at 2% to 100% mole/mole, relative to the compound of formula (III), in the presence of a 1,2-diamine as a ligand-forming substance (such as 1,2-diamino cyclohexane or ethylene diamnine) and at least 1 equivalent of a base (such as an alkali carbonate or an alkali phosphate. The article by A. Klapars et al. J. Am. Chem. Soc. 123, 7727 (2001) provides details of analogous preparations.

Method E

A compound of formula (I) may be prepared by conversion of a compound of formula (IV)

[where FG is a functional group which is convertible to R⁷ in one or more synthetic steps]. Functional group interconversions are standard procedures for a person skilled in the art. There are many methods described in the literature, which can be used as such or with modifications according to the functionalities present; Table A gives literature references (some of which also cite further appropriate references) which are specifically relevant to the preparation of a compound of formula (I) by the interconversion of FG to R⁷. It is apparent to the person skilled in the art that the literature examples given in Table A are not necessarily limited to the preparation of the specifically mentioned R⁷ but can be also applied by analogy to the preparation of other structurally related R⁷

A compound of formula (II), (III) or (VI) may be prepared, by functional group interconversion, from a compound of formula (V) [where FG is as defined above for a compound of formula (IV) and T is either halogen, amino, NHR¹, a protected amino group T′ (for example a carbamate, an amide, a cyclic imide, an N-alkyl-, N-alkenyl-, N-benzyl-, N-diphenylmethyl- or N-trityl-derivative, an imine derivative or an N-silyl- or N-disilyl-derivative) or a group T″ (that is, a group which may be converted to NH₂ or NHR¹ by applying synthetic methodology described in the literature; T″ being preferably azido, nitro, halogen, triflate, CONH₂, COOH, COCl or NCO)]. Starting from a compound of formula (V) the functional group FG may be converted to R⁷ by applying a method analogous to method E above. This conversion leads directly to a compound of formula (II) [when T is NHR₁], to a compound of formula (III) [when T is halogen (preferably chloro, bromo or iodo)] or to a compound of formula (VI) [when T is T′ or T″].

In a second step a compound of formula (VI) or (II) [when R¹ is other than H] can be converted to a compound of formula (II) [where R¹ is H] by either applying the methods [that is, deprotection or conversion of T″ to NH₂] as generically described above.

Examples of versatile values for T′ plus methods for deprotection are given in T. W. Green and P. Wuts, Protective Groups in Organic Synthesis, 3^(rd) edition (John Wiley & Sons 1999), Chapter 7.

Compilations of useful values for T″ plus literature to convert T″ into NH₂, T′ or NHR¹ can be found in M. B. Smith, Compendium of Organic Synthetic Methods, Vols. 1-10, Chapter 7 (Wiley, Vol. 10: 2002).

A compound of formula (II), (III) or (VI) may be prepared by a coupling reaction between a compound of formula (VII) and a compound of formula (VIII) [where Ra and Ra′ are each, independently, halogen (preferably Cl, Br or I), triflate or a metal-containing functionality containing, for example, B, Sn, Mg, Zn or Cu as the metal; examples are B(OH)₂, esters of boronic acid (preferably esters derived from 1,2- or 1,3-diols), trialkyltin (preferably Sn(CH₃)₃ or Sn(nBu)₃), a halogen salt of Mg, a halogen salt of Zn or Cu. If either Ra or Ra′ is a metal containing functionality, the other substituent must be halogen or triflate.

Such coupling reactions are widely known in the literature. Especially suitable are the Pd(0), Ni(0), or copper catalysed couplings which are well known to the person skilled in the art as Stille coupling, Suzuki coupling, Negishi coupling or Ullmann reaction. A comprehensive review of these reactions can be found in Metal-Catalysed Cross-Coupling Reactions; F. Diederich and P. Stang (eds.); Wiley-VCH; Weinheim 1998.

In a second step a compound of formula (VI) or (II) [when R¹ is other than H] can be converted to a compound of formula (II) [where R¹ is H] by either applying the methods [that is, deprotection or conversion of T″ to NH₂] as generically described above.

Surprisingly, it has now been found that the novel compounds of formula (I) have, for practical purposes, a very advantageous spectrum of activities for protecting plants against diseases that are caused by fungi as well as by bacteria and viruses.

The compounds of formula (I) can be used in the agricultural sector and related fields of use as active ingredients for controlling plant pests. The novel compounds are distinguished by excellent activity at low rates of application, by being well tolerated by plants and by being environmentally safe. They have very useful curative, preventive and systemic properties and are used for protecting numerous cultivated plants. The compounds of formula I can be used to inhibit or destroy the pests that occur on plants or parts of plants (fruit, blossoms, leaves, stems, tubers, roots) of different crops of useful plants, while at the same time protecting also those parts of the plants that grow later e.g. from phytopathogenic microorganisms.

It is also possible to use compounds of formula (I) as dressing agents for the treatment of plant propagation material, in particular of seeds (fruit, tubers, grains) and plant cuttings (e.g. rice), for the protection against fungal infections as well as against phytopathogenic fungi occurring in the soil.

Furthermore the compounds according to present invention may be used for controlling fungi in related areas, for example in the protection of technical materials, including wood and wood related technical products, in food storage, in hygiene management, etc.

The compounds of formula (I) are, for example, effective against the phytopathogenic fungi of the following classes: Fungi imperfecti (e.g. Botrytis, Pyricularia, Helminthosporium, Fusarium, Septoria, Cercospora and Altemaria) and Basidiomycetes (e.g. Rhizoctonia, Hemileia, Puccinia). Additionally, they are also effective against the Ascomycetes classes (e.g. Venturia and Erysiphe, Podosphaera, Monilinia, Uncinula) and of the Oomycetes classes (e.g. Phytophthora, Pythium, Plasmopara). Outstanding activity has been observed against powdery mildew (Erysiphe spp.) and rust (Puccinia spp.). Furthermore, the novel compounds of formula I are effective against phytopathogenic bacteria and viruses (e.g. against Xanthomonas spp, Pseudomonas spp, Erwinia amylovora as well as against the tobacco mosaic virus).

Within the scope of present invention, target crops to be protected typically comprise the following species of plants: cereal (wheat, barley, rye, oat, rice, maize, sorghum and related species); beet (sugar beet and fodder beet); pomes, drupes and soft fruit (apples, pears, plums, peaches, almonds, cherries, strawberries, raspberries and blackberries); leguminous plants (beans, lentils, peas, soybeans); oil plants (rape, mustard, poppy, olives, sunflowers, coconut, castor oil plants, cocoa beans, groundnuts); cucumber plants (pumpkins, cucumbers, melons); fibre plants (cotton, flax, hemp, jute); citrus fruit (oranges, lemons, grapefruit, mandarins); vegetables (spinach, lettuce, asparagus, cabbages, carrots, onions, tomatoes, potatoes, paprika); lauraceae (avocado, cinnamomum, camphor) or plants such as tobacco, nuts, coffee, eggplants, sugar cane, tea, pepper, vines, hops, bananas and natural rubber plants, as well as ornamentals.

The compounds of formula (I) are used in unmodified form or, preferably, together with the adjuvants conventionally employed in the art of formulation. To this end they are conveniently formulated in known manner to emulsifiable concentrates, coatable pastes, directly sprayable or dilutable solutions, dilute emulsions, wettable powders, soluble powders, dusts, granulates, and also encapsulations e.g. in polymeric substances. As with the type of the compositions, the methods of application, such as spraying, atomising, dusting, scattering, coating or pouring, are chosen in accordance with the intended objectives and the prevailing circumstances. The compositions may also contain further adjuvants such as stabilizers, antifoams, viscosity regulators, binders or tackifiers as well as fertilizers, micronutrient donors or other formulations for obtaining special effects.

Suitable carriers and adjuvants can be solid or liquid and are substances useful in formulation technology, e.g. natural or regenerated mineral substances, solvents, dispersants, wetting agents, tackifiers, thickeners, binders or fertilizers. Such carriers are for example described in WO 97/33890.

The compounds of formula (I) are normally used in the form of compositions and can be applied to the crop area or plant to be treated, simultaneously or in succession with further compounds. These further compounds can be e.g. fertilizers or micronutrient donors or other preparations which influence the growth of plants. They can also be selective herbicides as well as insecticides, fungicides, bactericides, nematicides, molluscicides or mixtures of several of these preparations, if desired together with further carriers, surfactants or application promoting adjuvants customarily employed in the art of formulation.

The compounds of formula (I) can be mixed with other fungicides, resulting in some cases in unexpected synergistic activities. Mixing components which are particularly preferred are azoles, such as azaconazole, BAY 14120, bitertanol, bromuconazole, cyproconazole, difenoconazole, diniconazole, epoxiconazole, fenbuconazole, fluquinconazole, flusilazole, flutriafol, hexaconazole, imazalil, imibenconazole, ipconazole, metconazole, myclobutanil, pefurazoate, penconazole, pyrifenox, prochloraz, propiconazole, simeconazole, tebuconazole, tetraconazole, triadimefon, triadimenol, triflumizole, triticonazole; pyrimidinyl carbinole, such as ancymidol, fenarimol, nuarimol; 2-amino-pyrimidines, such as bupirimate, dimethirimol, ethirimol; morpholines, such as dodemorph, fenpropidine, fenpropimorph, spiroxamine, tridemorph; anilinopyrimidines, such as cyprodinil, mepanipyrim, pyrimethanil; pyrroles, such as fenpiclonil, fludioxonil; phenylamides, such as benalaxyl, furalaxyl, metalaxyl, R-metalaxyl, ofurace, oxadixyl; benzimidazoles, such as benomyl, carbendazim, debacarb, fuberidazole, thiabendazole; dicarboximides, such as chlozolinate, dichlozoline, iprodione, myclozoline, procymidone, vinclozoline; carboxamides, such as carboxin, fenfuram, flutolanil, mepronil, oxycarboxin, thifluzamide; guanidines, such as guazatine, dodine, iminoctadine; strobilurines, such as azoxystrobin, kresoxim-methyl, metominostrobin, SSF-129, trifloxystrobin, picoxystrobin, BAS 500F (proposed name pyraclostrobin), BAS 520; dithiocarbamates, such as ferbam, mancozeb, maneb, metiram, propineb, thiram, zineb, ziram; N-halomethylthiotetrahydrophthalimides, such as captafol, captan, dichlofluanid, fluoromides, folpet, tolyfluanid; Cu-compounds, such as Bordeaux mixture, copper hydroxide, copper oxychloride, copper sulfate, cuprous oxide, mancopper, oxine-copper; nitrophenol-derivatives, such as dinocap, nitrothal-isopropyl; organo-p-derivatives, such as edifenphos, iprobenphos, isoprothiolane, phosdiphen, pyrazophos, tolclofos-methyl; various others, such as acibenzolar-S-methyl, anilazine, benthiavalicarb, blasticidin-S, chinomethionate, chloroneb, chlorothalonil, cyflufenamid, cymoxanil, dichlone, diclomezine, dicloran, diethofencarb, dimethomorph, SYP-LI90 (proposed name: flumorph), dithianon, ethaboxam, etridiazole, famoxadone, fenamidone, fenoxanil, fentin, ferimzone, fluazinam, flusulfamide, fenhexamid, fosetyl-aluminium, hymexazol, iprovalicarb, IKF-916 (cyazofamid), kasugamycin, methasulfocarb, metrafenone, nicobifen, pencycuron, phthalide, polyoxins, probenazole, propamocarb, pyroquilon, quinoxyfen, quintozene, sulfur, triazoxide, tricyclazole, triforine, validamycin, zoxamide (RH7281).

A preferred method of applying a compound of formula (I), or an agrochemical composition which contains at least one of said compounds, is foliar application. The frequency of application and the rate of application will depend on the risk of infestation by the corresponding pathogen. However, the compounds of formula I can also penetrate the plant through the roots via the soil (systemic action) by drenching the locus of the plant with a liquid formulation, or by applying the compounds in solid form to the soil, e.g. in granular form (soil application). In crops of water rice such granulates can be applied to the flooded rice field. The compounds of formula I may also be applied to seeds (coating) by impregnating the seeds or tubers either with a liquid formulation of the fungicide or coating them with a solid formulation.

A formulation [that is, a composition containing the compound of formula (I)] and, if desired, a solid or liquid adjuvant, is prepared in a known manner, typically by intimately mixing and/or grinding the compound with extenders, for example solvents, solid carriers and, optionally, surface active compounds (surfactants).

The agrochemical formulations will usually contain from 0.1 to 99% by weight, preferably from 0.1 to 95% by weight, of the compound of formula I, 99.9 to 1% by weight, preferably 99.8 to 5% by weight, of a solid or liquid adjuvant, and from 0 to 25% by weight, preferably from 0.1 to 25% by weight, of a surfactant.

Advantageous rates of application are normally from 5 g to 2 kg of active ingredient (a.i.) per hectare (ha), preferably from 10 g to 1 kg a.i./ha, most preferably from 20 g to 600 g a.i./ha. When used as seed drenching agent, convenient dosages are from 10 mg to 1 g of active substance per kg of seeds.

Whereas it is preferred to formulate commercial products as concentrates, the end user will normally use dilute formulations.

The following non-limiting Examples illustrate the above-described invention in more detail.

EXAMPLE 1

This Example illustrates the preparation of Compound No. 1.01.

2-Amino-4′-ethinyl-biphenyl (0.30 g) and 1-methyl-3-trifluoromethyl-4-chlorocarbonyl-pyrazol (0.33 g) were combined in THF under cooling with ice and then pyridine (0.12 ml) was added. After warming to ambient temperature the suspension was stirred for 3.5 hours, poured into water and extracted twice with ethylacetate. Separation of the organic phase, drying with sodium sulfate and evaporation of the solvent and chromatographic purification on silica gel (solvent: hexane:ethylacetate 2:1) yielded 0.4 g (70.2%) of Compound No. 1.01.

EXAMPLE 2

This Example illustrates the preparation of Compound No. 2.01.

To 1-methyl-3-trifluoromethyl-4-pyrrol carboxylic acid (0.22 g) dissolved in 10 ml dichloromethane were added triethylamine (0.32 ml) and 2-amino-4′-trimethylsilylethinyl-biphenyl (0.3 g) and finally, under cooling with ice, bis(2-oxo-3-oxazolidinyl) chlorophosphinic acid (0.29 g). After stirring for 18 hours the solvents were removed under reduced pressure and the residue was taken up with ethylacetate. Washing with water and brine, drying with sodiumsulfate and evaporation of the solvent yielded 0.45 g of a yellow oil which was chromatographed on silica gel (eluent: hexane:ethylacetate 2:1) to yield 0.13 g (26%) of Compound No. 2.01.

EXAMPLE 3

This Example illustrates the preparation of Compound No. 1.72.

To NaH (46 mg) in 5 ml dry THF at 0-5° C. was added 2-N-formylamino-4′-(propin-1-yl)-biphe (0.3 g) in 10 ml dry THF. The reaction was kept at this temperature for 1 hour and afterwards 1-methyl-3-trifluoromethyl-4-chlorocarbonyl-pyrazol (0.372 g) was added. The resultant suspension was stirred at room temperature overnight, poured into brine and extracted with ethylacetate. The solvent was evaporated and the the residue was taken into methanol and sodiummethylate (10 mg) was added. After 30 minutes the mixture was neutralised with diluted HCl, extracted with ethylacetate and washed until neutral. Chromatographic purification on silica gel (eluent: ethylacetate:hexane 1:2) and recrystallisation from toluene:hexane (4:1) yielded 0.169 g of Compound No. 1.72.

EXAMPLE 4

This Example illustrates the preparation of 2- amino4′-(trimethylsilyl)ethinyl-biphenyl (Compound No.12.02) and 2-amino-4′-ethinyl-biphenyl (Compound No.12.01) using a preparation according to Method F above.

To 2.5 g 2-amino-4′-bromo-biphenyl (WO0264562) in piperidine (25 ml) under nitrogen were added in sequence CuI (0.1 g), bis(triphenylphosphino)palladium dichloride (0.35 g) and trimethylsilylacetylene (2.8 ml). The mixture was stirred for 22 hours at room temperature and for a further 26 hours at 60° C. After cooling the reaction mixture was diluted with water and extracted with ethylacetate. Then the organic phase was washed with water and dried over sodium sulfate. After evaporation of the solvents in vacuum the mixture was chromatographed on silica gel (hexane:ethylacetate 9:1) to yield 2- amino-4′-(trimethylsilyl)ethinyl-biphenyl (2 g) (Compound No.12.02).

1.4 g of this compound was dissolved in methanol (40 ml) and potassium carbonate (0.9 g) was added with cooling. The resultant suspension was stirred for 2 hours, poured on ice-water and the precipitate formed was filtered off, washed thoroughly with water and dried to obtain 2-amino-4′-ethinyl-biphenyl (0.9 g) (Compound No.12.01) as light tan crystals.

The resultant dark mixture was diluted with water and extracted with ethyl acetate. The organic phase was washed with water, dried over sodium sulfate and the solvents were evaporated at reduced pressure. The residue was taken into acetonitrile and washed repeatedly with hexane. After removal of the acetonitrile at reduced pressure and chromatography of the residue with silicagel (eluent:hexane ethylacetate 2:1) 2-N-formylamino-4′-(propin-1-yl)-biphenyl (Compound No.12.16) (1.57 g) was obtained as a light yellow powder.

a) Preparation of 2-nitro4′(2,2-dichloro)ethylene-biphenyl.

To 2-nitro-4′formyl-biphenyl (2 g) (WO 95 03290) (prepared by Pd-catalysed coupling of 2-bromonnitrobenzene with 4-formyl-phenyl-boronic acid) in ethanol (70 ml) was added hydrazine hydrate (95%) (1.32 g) and the resultant mixture was then refluxed for 5 hours. The solvent was evaporated to dryness under reduced pressure, the residue was suspended in DMSO (30 ml) and then ammonia (25%) (3 ml), and freshly prepared CuCd (80 mg) were sequentially added and finally tetrachlorometane (3.8 g) was dropped in under cooling with water. The mixture was stirred at room temperature for 24 hours and the resultant green suspension was poured into water, extracted with dichloromethane, washed with water and dried over sodium sulfate. Evaporation of the solvent and chromatography of the residue over silicagel (eluent:hexane:ethylacetate 4:1) yielded 2-nitro-4′(2,2-dichloro)ethylene-biphenyl (0.8 g), m.p. 58-59° C.

b) Preparation of 2-amino-4′(2,2-dichloro)ethylene-biphenyl.

2-Nitro-4′(2,2-dichloro)ethylene-biphenyl (0.76 g) from step (a) was dissolved in 50% ethanol (30 ml) and heated to reflux. Then 2N HCl (0.3 ml) in 50% ethanol (10 ml) was added dropwise. The reaction mixture was held at reflux for 4 hours, cooled to room temperature and filtered. The filtrate was-neutralised with sodium bicarbonate, extracted twice with ethylacetate and the organic phase was dried over sodium sulfate. Evaporation of the solvent under reduced pressure yielded 2-amino-4′(2,2-dichloro)ethylene-biphenyl (0.62 g) (Compound No. 12.07).

c) 2-Amino-4′(2,2-dichloro)ethylene-biphenyl (3 g) was dissolved in 150 ml dimethyl sulfoxide in which 0.9 g KOH (85%, powder) has been suspended. The mixture was stirred over night at room temperature, diluted with excess of water and extracted twice with ethyl acetate and the organic phase was dried over sodium sulfate. Evaporation of the solvent under reduced pressure and chromatography of the residue over silicagel (eluent:hexane:ethylacetate 4:1) yielded 2.5 g 2-amino-4′(2,2-dichloro)ethylene-biphenyl as a tan coloured solid.

EXAMPLE 7

Step A: 2-Nitro-(4′-trimethylsilyl)-biphenyl

2-Bromo-nitrobenzene (0.86 g), 4-(trimethylsilyl)phenylboronic acid (1 g) and bis-(triphenylphosphine)-palladiumdich (0.3 g) were dissolved in dimethoxyetane (35 ml) and then a solution of sodium bicarbonate (1.3 g) dissoved in water (5 ml) was added dropwise. The mixture was heated for 3 hours (80° C. bath temperature), cooled to room temperature, poured on to ethyl acetate:water:1:1 (300 ml) and suction filtered. The organic phase was separated, dried over sodium sulfate and the solvent was removed. The resultant residue (1.58 g of a dark oil) was chromatographed on silica gel (eluent:hexane:ethyl acetate:4:1) to yield a yellow oil (1.12 g). This compound was used in Step B.

Step B: 2-Amino-(4′-trimethylsilyl)-biphenyl [Compound 12.18]

The compound obtainedfrom step A above (0.955 g) and ammonium formiate (1.86 g) were dissolved in methanol (30 ml) and purged with nitrogen. To this solution, Pd (100 mg; 10% on carbon) was added, in 2 portions. After stirring at room temperature for 15 hours, the reaction mixture was filtered and the solvent was evaporated.
